Editor's note
This study signals potential future regulatory and operational pressures on engineered stone fabrication. Importers and project buyers should anticipate possible supply chain disruptions or cost increases as shops implement stricter safety controls, mandatory respirator use, and enhanced dust mitigation systems to comply with evolving occupational health standards.
A study by Georgia Tech researchers, published in Oxford Academic, identifies significant health hazards for workers in engineered stone fabrication shops. Engineered stone slabs can contain over 90% crystalline silica, far exceeding the typical 40% or less found in natural granite or marble. During cutting and shaping with powered tools, respirable silica dust is released, posing a high risk of lung inflammation and acute silicosis. The research, based on air-sampling data from 11 Georgia fabrication shops over six years, found all workers in a shop are at risk, not just those directly cutting the material. The team recommends all workers wear respirators, with powered air-purifying respirators for the most exposed employees.
Research from Georgia Tech's Safety, Health, and Environmental Services (SHES) program highlights a critical safety distinction between natural and engineered stone. Engineered stone, popular for countertops, can contain over 90% crystalline silica, compared to 40% or less in natural granite or marble.
Fabrication processes like cutting and polishing with powered tools release respirable silica dust, which can cause acute silicosis. The study, involving air sampling at 11 fabrication shops in Georgia, categorizes workers into four risk groups and finds everyone in a shop is exposed, not just cutters. The findings were published in Oxford Academic.
The research team's primary recommendation is the mandatory use of respirators for all workers, with higher-grade protection for those with the most exposure.
